Nginx 403 forbidden error

I’m brand new to docker, I was going through the tutorial and ran into this issue:

Inserting localhost on my web browser (Chrome) produces the same error. I have done nothing besides docker installation and the tutorial, so I really don’t know what could cause this failure. This was also reproduced when using the Command Prompt.

Issue type: Tutorial-Web Server

OS Version/build: Windows 10 Enterprise

App version: Docker version 18.03.0-ce, build 0520e24

Steps to reproduce: See image
